John Ross Bowie, who portrayed the guys’ frenemy Barry Kripke, is set to the join the upcoming The Big Bang Theory spin-off on Max, according to an exclusive report from Deadline.

Bowie joins Kevin Sussman (Stuart), Brian Posehn (Bert) and Lauren Lapkus (Denise) in signing on for the yet-to-be-titled show, which now features a roster of secondary characters from The Big Bang Theory universe.

Bowie appeared in twenty-five episodes of The Big Bang Theory, starting in its second season and making his final appearance in the penultimate episode. Although Barry Kripke was regularly in the orbit of Sheldon and the gang, working at the same university, he wasn’t particularly friendly with any of them. Kripke had a notably adversarial relationship with Sheldon, often mocking or pranking him.

Apart from The Big Bang Theory, Bowie’s credits include a starring role in the ABC sitcom Speechless, which ran for three seasons from 2016 to 2019. He also had a recurring role on the Chuck Lorre-created show United States of Al.

In December last year, Deadline reported that Chuck Lorre would be joined by The Big Bang Theory co-creator Bill Prady and feature film writer Zak Penn (Ready Player One, Free Guy) to write the script and executive produce the show.

The untitled project is still in development and has not been greenlit by Max, the streaming service owned by Warner Bros. Discovery.
